Jörg-Peter Elbers joins OFC panel to debate 100G line side standards and optimum technology for shorter links

Debate to examine the benefits and challenges of PAM4 as a low-cost alternative to coherent detection

  • Panel: Jörg-Peter Elbers, SVP, advanced technology, ADVA; Larry Johnson (moderator), president, FiberStory; Tim Yount (moderator), co-founder, Fiber Insight (FI); Richard Ednay, technical director, OTT; John D’Ambrosia,  senior principal engineer, IP standards team, FutureWei Technologies; Mark Filer, principal optical network architect, Microsoft Azure; Radha Nagarajan, CTO, optical interconnect, Inphi; Gert Sarlet, product line manager, Finisar; Muhammad Sarwar, global product planner, Fujitsu Network Communications
  • Topics: Line side 100Gbit/s DWDM network solutions – debating the options
  • When: Thursday, March 7, 1:15 p.m.
  • Where: OFC, The Optical Networking and Communication Conference & Exhibition, San Diego Convention Center, San Diego, California, USA

Today’s long haul standards-based DWDM deployments for 100Gbit/s and higher feature very high dispersion tolerances, but are very expensive to deploy and complex to manage. Many companies deploying 100Gbit/s line side DWDM are willing to step outside the box to consider lower cost alternatives. This panel discussion looks at 100Gbit/s line side standards and discusses alternatives for limited distance links. A chromatic dispersion limited DWDM line side version of PAM4 is gaining popularity as a low cost alternative to coherent detection receivers, although no industry standard exists today supporting this approach.

Jörg-Peter Elbers and a panel featuring private network operators, data center interconnect players, network equipment providers and industry standards representatives will give their thoughts on each approach.
